Pass viewbag to partial view from action controller

Question

I have a mvc view with a partial view.There is a ActionResult method in the controller which will return a PartialView. So, I need to pass ViewBag data from that ActionResult method to Partial View.

This is my Controller

public class PropertyController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }
    public ActionResult Step1()
    {
        ViewBag.Hello = "Hello";
        return PartialView();
    }
}

In Index.cshtml View

@Html.Partial("Step1")

Step1.cshtml partial view

@ViewBag.Hello

But this is not working. So, what is the correct way to get data from viewbag. I think I'm following wrong method. Please guide me.

Answer 1

You can use it as mentioned below :

In your View :

@Html.Partial("[ViewName]", (string)ViewBag.Message)

And Your partial View :

@model String

<b>@Model</b>

As Shown Above ViewBag.Message will be passed to the partial view. and in your partial view you can use it as a @Model.

Note : here type of ViewBag.Message is string. You can pass any type.

Answer 2

If you don't have to use ViewBag, you can use TempData. TempData is shared for the whole execution chain.

public class PropertyController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }
    public ActionResult Step1()
    {
        TempData["Hello"] = "Hello";
        return PartialView();
    }
}

In Index.cshtml View

@Html.Partial("Step1")

Step1.cshtml partial view

@TempData["Hello"]
